1 / 10 page TSOP344..SS1BS12 Document Number 82272 Rev. 1.1, 28-Feb-05 Vishay Semiconductors www.vishay.com 1 16672 1 2 3 IR Receiver Modules for Remote Control Systems Description The TSOP344..SS1BS12 - series are miniaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. TSOP344..SS1BS12 is a standard IR remote control receiver series for 3 V supply voltage, with excellent suppression of distur- bance signals. Features • Photo detector and preamplifier in one package • Internal filter for PCM frequency • Improved shielding against electrical field disturbance • TTL and CMOS compatibility • Output active low • Supply voltage: 2.7 V to 5.5 V • Improved immunity against ambient light Mechanical Data Pinning: 1 = OUT, 2 = GND, 3 = VS Parts Table Block Diagram Application Circuit Part Carrier Frequency TSOP34430SS1BS12 30 kHz TSOP34433SS1BS12 33 kHz TSOP34436SS1BS12 36 kHz TSOP34437SS1BS12 36.7 kHz TSOP34438SS1BS12 38 kHz TSOP34440SS1BS12 40 kHz TSOP34456SS1BS12 56 kHz 30 k Ω 2 3 1 VS OUT Demo- GND Pass AGC Input PIN Band dulator Control Circuit 16833 C1 = 4.7 µF TSOPxxxx OUT GND µC R1 = 100 Ω +VS GND Transmitter with TSALxxxx VS R1 + C1 recommended to suppress power supply disturbances.
